Answer 1

The null hypothesis is that there is no change in students' beliefs about illegal drug use as they go through college.

Step-by-step explanation:

The null hypothesis for this study is that there is no change in students' beliefs about illegal drug use as they go through college. In other words, the proportion of students who think that illegal drug use is wrong is the same before and after college. The scientist will compare the responses of the same 104 students before and after college to determine if there is a significant difference.
